Product details

It carries a 15 kW rating at 400 V in AC-2 duty (slip-ring motor starting) and a 15.5 A rating at 400 V in AC-4 duty (plugging/inching).

The AC-2 rating of 15 kW at 400 V is the spec that governs motor starting on slip-ring or wound-rotor motors — common in crane or conveyor drives where the rotor resistance is stepped out.

Main circuit terminals accept solid conductors up to 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or max. 2x (0.75...4 mm²), and stranded conductors up to 2x (0.75...25 mm²). The minimum permissible cross-section at 40 °C is 16 mm². For the coil terminals, solid or stranded wire from 0.75 to 16 mm² is accepted.

The part carries a substance prohibitance date of 05/01/2012, aligning with RoHS compliance. The SIRIUS series typically carries UL, CSA, and CE certifications, though specific approval markings for this variant should be verified on the nameplate. The standard documentation package includes a datasheet and declaration of conformity.
